Abstract

Purpose: To report the patterns of care for brain metastases (BMs) in the Federation of Asian Organizations for Radiation Oncology (FARO).

Methods: Overall, 37 questions were prepared. The survey was conducted online using Google Forms, and the URL was distributed to members of the FARO research committee. Radiation oncologists associated with FARO responded to the questionnaire between May 2023 and June 2023, and their answers were analyzed.

Results: Responses were received from 32 radiation oncologists in 13 countries participating in FARO. Twenty-six physicians (81.3%) were affiliated with academic centers, and 22 (68.8%) were able to perform stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (fSRT) for BMs at their institution. The most typically used prognostic index for BM was the recursive partitioning analysis classification (17 physicians, 53.1%). The maximum number of BMs indicated for SRT/SRS was ≤three (11 physicians, 34.4%), whereas eight (25.0%) physicians answered for 6-10 BMs. The maximum size of BMs considered for SRS/fSRT was ≤3 cm (14 physicians, 43.8%), whereas nine (28.1%) answered that SRS/fSRT was preferred if the maximum size was >4 cm. When whole-brain radiotherapy (RT) was indicated, hippocampal avoidance and memantine usage were limited to 50.0% and 25.0% of patients, respectively. The most typical RT modality after BM resection was SRS/fSRT alone, regardless of whether the margin was positive (19 physicians, 59.4%) or negative (13 physicians, 40.6%).

Conclusion: We report the survey results of the patterns of care for BMs in the FARO. This survey was conducted only among a limited number of FARO members. Since many respondents were affiliated with relatively large-scale academic centers, large-scale surveys, including community hospitals, are warranted for future initiatives.

亚洲脑转移瘤的治疗模式:亚洲放射肿瘤学组织联合会开展的真实世界调查。
目的:报告亚洲放射肿瘤学组织联合会(FARO)对脑转移瘤(BMs)的治疗模式:方法:共准备了 37 个问题。调查使用谷歌表格在线进行,并将 URL 分发给 FARO 研究委员会成员。2023 年 5 月至 2023 年 6 月期间,与 FARO 相关的放射肿瘤学家对问卷进行了回复,并对他们的答案进行了分析:共收到来自 13 个参与 FARO 的国家的 32 位放射肿瘤学家的回复。26名医生(81.3%)隶属于学术中心,22名医生(68.8%)能够在其所在机构对BM进行立体定向放射手术(SRS)或分割立体定向放射治疗(fSRT)。最常用的BM预后指标是递归分割分析分类(17名医生,53.1%)。用于 SRT/SRS 的最大 BM 数量≤3 个(11 名医生,34.4%),而 8 名医生(25.0%)的回答是 6-10 个 BM。SRS/fSRT 考虑的最大 BM 大小≤3 厘米(14 名医生,43.8%),而 9 名医生(28.1%)回答如果最大 BM 大于 4 厘米,则首选 SRS/fSRT。当需要进行全脑放疗(RT)时,海马回避和美满霉素的使用分别仅限于 50.0% 和 25.0% 的患者。无论边缘是阳性(19 名医生,59.4%)还是阴性(13 名医生,40.6%),脑干切除术后最典型的 RT 方式都是单纯 SRS/fSRT:我们报告了 FARO 对乳腺肿瘤治疗模式的调查结果。这项调查仅在有限的 FARO 成员中进行。由于许多受访者隶属于规模相对较大的学术中心,因此今后有必要开展包括社区医院在内的大规模调查。
